GOMBINED RAIL-FASTENING AND TIE-PLATE.

SPEGIFIGATIQN forming part of Letters Patent No. 744,606, dated November17, 1903.

Application filed March 10, 1903. Serial No- I4='7,15'7. (No model.)

To all whom it may concern:

Be it known that we, RUDOLF'GEORGPOL: STER, manufacturer, and ADAM LOEW,engineer, subjects of the Emperor of Germany, residing atWorms-Pfiffligheim, Prussia, Germany, have invented certain new anduseful Improvements in a Combined Rail-Fastening and Tie-Plate, of whichthe following is a specification.

Our invention relates to a combined railfastening and tie-plate forrailroads; and it particularly consists in the special means forsecuring the rail in position on the tie-plate, which means allow aquick locking and unlocking of the said rail. Furthermore, theconsiderable loss of little iron fittings is avoided, which less formsan inconvenience" Figure 1 shows a plan view of our combined fasteningand tie-plate with a rail secured in position, parts of which are cutaway. Fig. 2 is a longitudinal section through the said arrangement;Fig. 3, a cross-section thereof. Figs. at to 9 illustrate details. Fig.10 is a perspective view of the said arrangement.

In the construction of our invention we use a rectangular tie-plate a,which has the usual obliquely-depressed bed or seat 'for receiving therail-foot. formed to a hook-shaped clamp d, grasping over the adjacentflange of the rail. On the other side thereof alongitudinal slot e iscentrally cut out from the bed portion of the plate a. vertically totherail, and a movable clamp q'is guided within said slot and holdtherein by means of twoprojectiug flanges h on both sides of saidmovableclamp. (See Figs. 2, 3, 5, and Bolts b are provided in suitablebolt-holes for securing the plate a on the tie c, and a suitable recessor groovef is cut out from the upper surface of said tie for receivingtherein the base portion of clamp g and allowing same to move freelywithin said groovefand slot (2;

A flat wedge or keyz' is provided for securing the movable clamp ginposition on the adjacent flange of the rail, and the rear side of theclamp g and'theelevated or nondepressed portion of thetie-plateoppositely thereto are slotted for receiving said wedge The one end ofsaid plate isthe under side of the head thereof is beveled on one side,as clearly illustrated in Figs. 7, t

8, and 9.

From the foregoing description it will be clear that for laying therails it is only required for the layers to carry with them a pluralityof wedges and spikes, as the whole plate a, With bolts b and clamp g,may be alreadyfastened to the tie before the same is brought on thetrack. By this manner the considerable loss of little iron fittings isavoided, and the rails may be laid within a comparatively short time.

Having now described our invention, we claim- 1. In a combinedrail-fastening and tieplate, the combination of a tie-plate, a depressedrail-bed portion therein, a rigid railclamp formed on the one end ofsaid plate, a longitudinal slot within said plate, a movable rail-clampguided therein, provided with a groove, for guiding ahorizontally-movable wedge or key for securing said second clamp in itsfastening position and means for securing said wedge or key wheninserted, substantially as described.

2. In a combined rail-fastening and tieplate, the combination of atie-plate, a vertically-adjustable, rigid rail-clamp at the one endthereof, a movable rail-clamp guided in a longitudinal slot, providedwith a groove, a wedge guided therein for holding said latter clamp inits fastening position, two crossed slots in the wedge or key and thetie-plate, a spike driven through said slots for securing the wedge orkey in position, substantially as described.
